expandAmatrix | R Documentation |
Expand a current A matrix with a new pedigree. The parents in the new pedigree should also be in the A matrix.
expandAmatrix(newPedigree = NULL, A = NULL, returnAll = TRUE)
newPedigree |
pedigree data name (3-column way format). Unknown value should be equal 0. |
A |
numerator relationship matrix output from Amatrix function. |
returnAll |
if TRUE returns old A with new A, if FALSE returns only new A |
Matrix with the Relationship between the individuals.

#Computing additive relationship matrix:
